"We had just purchased our home and after a few days found that the septic system was having a problem - it smelled terribly. A septic contract was a required part of the purchase, however, after 2 months that company was making no headway in getting it fixed and we were unhappy and our neighbors were becoming annoyed with the smell too (understandably so.) We decided to try Total Septic upon recommendation of another neighbor. They were able to schedule our service for the next day. After a few minutes diagnostics, their technician felt confident he knew the issue and went to go get parts. That same afternoon, he replaced the air pump and verified aeration of the tank and explained it would take about 4-7 days to clear the smell. It did and we are extremely happy. I'm not the greatest fan of "star" ratings, but to explain my own below: 1) Work Quality 4.5/5, could it have been better (how it was mounted, setup, etc, yes, but for the price, I think they did a great job and anything more, probably would have required more time and more planning, nonetheless, those options weren't presented, so as close to a '5' as you can get. 2) Customer Service - Absolutely a '5' - Hands down excellent. They did not require a bunch of coordination or paperwork before coming out, they just made the appointment and fixed the problem asking for payment immediately after. We also chose to sign a support contract with them so we can continue to enjoy their excellent service. 3) Value for the money - I had priced replacement pumps and thought that was the problem, but I would be taking a gamble that my uneducated diagnosis from internet information was wrong. I received expert service and experience as well as same-day replacement for nearly the same price. In summary, I could not be happier with the service and people at Total Septic!"

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.

Many contractors offer warranties for parts and labor. Confirm terms before hiring.
